See, I don't understand how everyone believe that Jon is trying to meddle in the conflicts of the realm and its wars, thus breaking his oath...

The Bastard made a direct threat to Jon and he's acting on it..is that against his vows?...At least, that's how I interpret it..he also didn't command the Night Watch to join him, it was their choice of whoever wanted to ride south with him

You have more luck then I do...I tried convincing one friend to read the books, rather than wait for the shows, she tells me she doesn't want to ruin the show by reading the books..what?!?!? I lost it! should be the other way around, you don't want to ruin the books by watching the show!

My events may be iffy, been awhile..but I wondered the same..Ned would have declared for Stannis, I couldn't imagine why Robb didn't want to follow his fathers footsteps...originally I believe he just marched to save his sisters and avenge his father, and somewhere in there, I think his own bannermen styled him King in the North, and Robb just went along with it

Eh, I don't know... I believe the Boltons were never truly loyal to the Starks, with Neds death, Roose saw this as a chance to climb the ladder, in other words, he would have done the same, without or without Robbs mistakes
